摘　　要：通过对湖北东部500kV双环网实际运行电压水平及无功潮流分析,确定了枯小方式电压偏高、层间无功潮流倒送、大负荷期间电容器投运率低的原因,提出了加强发电机组进相管理、电缆集中区域感性补偿、500kV变电站抽头调整建议,供500kV双环网规划、设计及运行部门参考。This article analysed the actual voltage level and reactive power flow of Hubei eastern 500kV double loop grid,confirmed the reason caused higher voltage in dry and low load mode,interlayer reactive power flow backfeed,low capacitor usage rate in heavy load,put forward suggestions of strengthening generator unit in leading phase operation,inductive compensation in cable amass area,and 500kV substation transformer tapping adjustment.It offers the reference for 500kV double loop gric on scheme,design and operation..
